ME TALLIC RAILWAY-TIE Specification of Letters Patent.

Patented May 4, 1909.

Application filed December 26, 1908. Serial No. 469,206.

provide a simple, strong, light andinexpensive tie to which one or more rails can be My invention aims to provide-ametallic tie of a form that can be readily made in fastening the rail.-

steel or other desired metals and to which rails can be fastened in the usual well known simple manner.

A further object of my invention isto' provide a metallic tie adapted to receive and firmly hold a stool or support constructed of wood'or a like material for supporting and struction I obtain a high degree of resiliency,

Y strength and superior lasting quality of the tie.

. The invention also consists in compressing or compacting the stool block thus rendering the said blocks more dense andgreatly increasing the holding power of the sp1kes.

I prefer to use wooden stool'blocks treated with some wood reservative, such as sulfate of zinc which wi l render the blocks practically indestructible except by mechanical forces.

In the accompanyin drawings Figure 1 is a plan view of the pre erred form of my improved tie. Fig. 2 is a longitudinal section through line 22 of Fig. 1. Fig. 3 a section on line 3-3 of Fig. 2. Fig. 4 is a section on line 44 of Fig. 2. Fig. 5 is a broken enlafrged perspective view of my preferred form 0 tie.

My improved tie A, is cast from steel or other metal, and is preferably -nnade integral that is of one continuous piece, andv comprises a base plate B tel}; plate 0 between which is an open space I, From the base plate B separated at a distance from one anotherequal to the space between the track rails are boxtie receptacles H bounded by side walls FF and end walls E and G the side walls F tapering toward the ends of the By this combined 0on tie. in vertical walls ff to insure stiffness and rigidity to the said walls F-F. Stool blocks I-l for sup ort of the rails TT are fittedand held firm y in the said box like receptacles H by means of spikes or bolts K which enter through the openings h in the side walls F. Drainage holes a are provided at the bottom plate B forming the lower por-, tion of the receptacles H. The sides of the plates B and C are preferably provided with a sli ht bead I) thus strengthening the ma teria at this portion where it is most subject to blows and shocks. The stool blocks are preferably made u of several sectionsas shown in Fig. 3 as c eaper aswell as sounder and stronger material can thus be obtained. The rails are secured to the stool blocks by means of any desired form of spike or other holding means S.

This tie when set with its base upon the road bed offers an ample surface for contact with the ballast to hold it firml in place, tamping of the ballast being rea il r accom plished underneath the plate B, in the openmg D, and at the ends E. The rail being bolted upon the yieldable blocks I, the vibration resulting from the passage of train is absorbed thereby, this bein aided by the peculiar 0 en arrangement the plates and 0; Furthermore it will be evident that by the use of a minimum amount of materiala maximum strength is secured, insuring economy in the manufacture and transportation and laying of the ties.

l5, provided It will be evident from an inspection of the drawing that I rovide a tie wherein 'reat stiffness is obtained in a horizontal plane, and resiliency is retained in the vertical plane, the binding plates B and C lying in a iorizontal plane am being of a comparatively thin vertical section, and thus exceedingly resilient and flexible, allowing of vertical motion for adjustment of the tie in respect to the road bed as the weight'of trafiicpasses .over the rail.

Having thus described my invention, I claim as new and desire to secure by Letters Patent' 1. A metallic tie comprising separatedhorizontally disposed 'base and top plates provided with box-like receptacles located at either end thereof, the said receptacles being into rally formed with the said base and top p ates which plates are otherwise not connected one with the other, whereby vertical resiliency of the'tie is obtained, as and for the urpose specified.

, 2. A metallic tie comprising horizontally disposed base plate provided with box-like receptacles at either end of the same, a top late integrally formed with the inner end Walls defining the said receptacles. the said top and bottom plates being integrally connected one with the other solely by means of the end walls of the said receptacleswhereby vertical resiliency of the tie is obtained, as shown and described. i

3. The combination with a metallic tie comprising horizontallydisposed separate base and top plates, box-like receptacles at either end of said plates integrally formed therewith, the said base and top plates being connected with each other solely by means of the'i'nner end walls of the aforesaid receptacles whereby a resilient and flexible tie is obtained.

4. The combination with a metallic tie comprising horizontally disposed separate base and'top plates, boX-like'receptacles at either end of said plates integral; iorlned therewith, the said base and top plates being integrally connected with each other solely by means of the inner end walls of the aforesaid receptacles and yieldable blocks secured either end of the said lat-es integra y formed therewith, the said p ates being se arated or not in contact'with each other t roughout their central portion but being integrally connected with each other solely by means of'the inner end walls of the aforesaid receptacle whereby a resilient and flexible con- 7 strnction of tie is obtained.

In testimony whereof, I have slgnecl my name to this specification in the presence of two subscribing witnesses.
